Complete Question
Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89 z. Assume that the conditions for inference were met.calculate the p-value for Ellie's significance test
Answer:
The p-value is
Step-by-step explanation:
From the question we are told that
The percentage of senior citizens is p = 0.10
The sample size is
The sample proportion is
The test statistics is
The null hypothesis is
The alternative hypothesis is
Generally the p-value is mathematically represented as
From the z-table

<h3>we know that</h3><h3></h3><h3>the equation of a circle is</h3><h3>(x-h)²+(y-k)²=r²</h3><h3>where the center is the point (h,k)</h3><h3>r is the radius </h3><h3>if the center is the origin</h3><h3>so</h3><h3>(h,k) is (0,0)</h3><h3></h3><h3>the radius is the distance from point (0,5) to the origin (0,0)</h3><h3>r=√[(-5)²+(0)²]-------> r=√25---------> r=5 units</h3><h3></h3><h3>the equation is</h3><h3>(x-h)²+(y-k)²=r²------------> (x-0)²+(y-0)²=5²----------> (x)²+(y)²=25</h3><h3></h3><h3>Does the point (–3, –4) also lie on the circle?</h3><h3>the distance from the center to (–3, –4) is</h3><h3>d=√[(-4)²+(-3)²]-------> d=√25--------->d=5 units</h3><h3></h3><h3>d=r</h3><h3>therefore</h3><h3>the point (-3,-4) also lie on the circle</h3>
Step-by-step explanation :
Dado que Conner y Jana se multiplican (3568)(39610). El trabajo de Conner El trabajo de Jana (3568)(39610) = 35 + 968 + 10 = 314618 (3568)(39610) = 35⋅968⋅10 = 345680 ¿Es correcto cualquiera de ellos?
Jana y Conner están multiplicando dos números dados. Así que la pregunta es
3568 x 39610
0000
3568x
21408xx
32112xxx
10704xxxx
--------------------------------------
141328480
Así que la respuesta correcta es 141328480.
También los números se pueden agrupar como
3568 = 3000 + 500 + 60 + 8
39610 = 30000 + 9000 + 600 + 10
Después de agrupar multiplicando ambos términos obtenemos la respuesta requerida.
Así que ninguno de los dos tiene la respuesta correcta.
